The standard height of an interior door is typically 80 inches.
Understanding Standard Interior Door Heights
Interior doors are designed with standard dimensions to ensure compatibility with most residential and commercial building constructions. While there's a primary standard, some variations are recognized.
The most common and widely accepted height for an interior door is 80 inches. This measurement translates to 6 foot, 8 inches. Because of this conversion, 80-inch doors are frequently referred to in the industry as "6/8 doors."
Variations and Minimum Requirements
Although 80 inches is the standard, some building codes may permit slightly shorter doors. For instance, certain codes allow for interior doors with a height of 78 inches. A door measuring 78 inches is equivalent to 6 foot, 6 inches and is often known as a "6/6 door."
It's important to note that 80 inches is generally considered the minimum required height for interior doors in many areas, though the 78-inch option exists where allowed by local regulations.
Here's a quick reference for standard interior door heights:
| Height (Inches) | Height (Feet & Inches) | Common Industry Term | Notes |
|---|---|---|---|
| 80 | 6 foot, 8 inches | 6/8 door | Most common standard height |
| 78 | 6 foot, 6 inches | 6/6 door | Permitted by some building codes as a minimum |
Understanding these standard measurements helps in selecting the correct door for renovation projects, new constructions, or simply replacing an existing door.
